%X This work is part of an experimental contribution approach to the study
of the incorporation of glass sand from the grinding of recycled glass waste in
cement mortars and its influence on the physical and mechanical behavior of
semi-rich mortars without adjuvants. For this purpose, after a physical
characterization of the sands, eight (08) formulations of mortars based on
cement CEM II B/L 32.5R and fine sands (0/2) of glass at mass contents of 0%,
10%, 20%, 30%, 40%, 50%, 75% and 100% of the silty sand (0/2) were made
respectively to three (03) types of fine glass sand (white, brown, green) with
water dosages on cement (W/C) of 0.50, 0.45, 0.40. The results obtained show
that the fine sands of recycled glass have a higher water absorption than the
silty sand and the physical properties of the mortars prepared are affected by
the increase in the glass content. The mechanical performances are obtained for
the ratio W/C</span><span style=\"font-family:&quot;\"> </span><span style=\"font-family:Verdana;\">=</span><span style=\"font-family:&quot;\"> </span><span style=\"font-family:Verdana;\">0.50 and the formulation
of glass mortars for an optimal compressive strength superior to glass-free
mortar requires a substitution of 10% for fine white glass sand, 20% for sand
fine green glass and 75% for fine brown glass sand. The comparative study
between these different compositions of fine glass sand mortars shows that the
mechanical performances of fine brown glass sand </span><span style=\"font-family:Verdana;\">are</span><span style=\"font-family:Verdana;\"> better than other glass sands but generally remain
inferior to the control mortar based on natural silty sand.
